Ups and downs of biodiversityafter mass extinction unveiled

Marine animal groups like ammonoids and conodonts already peaked three or four million years earlier, namely still during the Early Triassic, researchers say.

The climate after the largest mass extinction so far 252 million years ago was cool, later very warm and cool again. Thanks to the cooler temperatures, the diversity of marine fauna ballooned, as paleontologists from the University of Zurich have reconstructed.

The warmer climate, coupled with a high CO2 level in the atmosphere, initially gave rise to new, short-lived species. In the longer term, however, this climate change had an adverse effect on biodiversity and caused species to become extinct.

Until now, it was always assumed that it took flora and fauna a long time to recover from theā€¦
